I'm getting ready to buy some wheels for my 2k accord 4 lug. I found a good deal on some 18x7.5" wheels that I like and they have a 42 offset. Is that ok,are they going to set in or stick out too far??
also,I have an eibach pro-kit(1-1/2" drop) should i go with the 225/40 or 215/40,when using these 42 offset wheels?

 

That's probably the most common offset that guys use with 18x7.5" wheels on 6th gen Accords (probably because it seems to be the most common offset in that size and lug pattern). So the 42 should be fine. I'd expect some small amount of rubbing in the rear. It may require trimming of the plastic tab on the rear bumper, or rolling of the fenders if you camber is corrected back to stock specs. With uncorrected camber, a prokit drop, and 42 offset wheels with 225/40...I'd say you'll probably only rub with people in the back, or under hard cornering, and most of that will be alleviated by trimming the bumper tab.

I have 45 offset in 18x7.5 with 225/40 tires. With uncorrected slight neg camber in the rear, I never rubbed for two years, with people, luggage, never rubbed. So when I got another new set of 18x7.5 I made sure I got 45 again, cause my friends with 42 had some slight rubbing. Now I've corrected my camber, and it only occasionally rubs if I have people in the back or under hard cornering.

I'm rambling...bottom line...you should be fine. Get 45 if you can, but if you can't find any in 45 that you like, then get the 42's.

 

My Racing Hart M5's are +42mm offset running Eibach Prokits and camber kit, I don't rub at all in the rear. But I'm a coupe.

 

I am about to replace my 17 inch rims with some 18's. I have the Neuspeed sport springs in my 98 sedan. I have a 2.2 front drop with a 2 drop in the rear. My tires are the 215/45/17, that rub with people in the back. I want the 18's bad, but the rubbing might be very bad with the drop that I have.

 

I rub some with my +43mm 18x7.5" wheels with 225/40-18 tires on my 6th gen Sedan. Chances are you will have some rubbing, and it may or may not be a problem depending on how much weight you carry on a regular basis, whether or not you have rear camber correction, and what your rear spring rates are...

I suggest you get 215/40-18 to eliminate rubbing, but you will have less sidewall (don't know if that'd be a problem). However, 215/40-18 tires will fit nice and square on the 7.5" wide rim, so it could reduce sidewall flexx and improve cornering if you're feeling adventurous Also the 0.1" decrease could help imrove your gearing, lol

yeah, the 6th gen coupes seem to have even more clearance than the sedan. That's also the reason why a 1.5" drop looks lower on a sedan than on a Coupe (coupe has more wheel gap due to higher cut fenderwells).

Just seems as though people with your setup who claim they don't rub have coupes :dunno:

 

Their are several mfg. making +45mm or higher wheel offset (backspacing or rather less back spacing).

Kosie and BBS wheels offer 114.3x4 in both 17" and 18" combo's
I think BBS wheels from tire rack are +47mm offset if I recall.

In addition, since in most cases a set of aftermarket wheels and tires could run $1200, 2000, 24000, etc. I might even suggest buying a second set of springs. You could use just the rears incombination with a camber kit or use the entire new set of springs.

H&R sells a set of OE sport springs 3/4" mild drop.
Comptech Sells an Accord set of springs which are more aggressive then OE sports but less so then Prokits for a good drop. Compared to tires or rims springs are dirt cheap, even good ones.

The other choice is talk things over with your suspesion shop in the rear, I find my tire guy will work with me on anysettings. We had other employees get in my truck to weigh down the rear to verify my tires wouldn't rub. A nice compromise might be to go halfway between droped off camber and OE stock camber, I'd much rather rotate tires a bit then ever rub in the fender wells.

Or if you are getting a body kit installed have the body shop trim the inside of rear fender well and apply some of the paint used to paint the kit as touch up paint inside the rear wheel well once it is trimmed, no one will ever know you did this if done correctly.
